The thing is that the audio cant be heard. I was animating and I added sound for the first time. It was working fine. Then I decided to continue later and I saved the file. The next time I opened the animation the sound layer has only one frame and nothing can be heard. I tried to delete the sound layer and add a new one with the same audio file but it didn’t work. i tried opening the animation again but that didn’t work either. The drawings are still fine it’s only the audio.

I’m using version 6.1.1 and the audio is an mp3 file
I would like to continue with the animation soon so I would really appreciate a reply

First I’d encourage you to update to our nightly build since we’re constantly improving, adding new features and fixing bugs. We also released v0.6.2 recently but that build unfortunately includes a copy/paste bug…

when that’s said, it sounds like your audio file has become corrupted somehow… Have you verified that it contains audio?

You mention that you tried re-adding the sound file but it didn’t work, you could please elaborate on that?

I second @CandyFace’s instructions. It is also possible that your audio is using an unsupported codec. If this is issue, you should be able to fix this by importing your sound into an audio editing application (I recommend the free program Audacity) and exporting the audio as .wav file.

@SnailLeader Hi. Please let us know if the answers that were previously left by Pencil2D’s developers have helped you.

Try out changing the sound file format as described with the free audio editor “audacity” (http://audacityteam.org)

Try importing the same file that you used in a “new” pencil2D file to see if it works.

If it does, then that means something has damaged your file on the animation file, and we’d urge you to send it to us for further review. (You can use dropbox, google drive, mega or whatever cloud storage service you trust, we’d just need a link to the project file)

If it doesn’t, then it means it’s the file itself, and the way it was made is not compatible with Pencil2D.

Please follow this guide to prevent losing your work and also learn how to extract the file contents, what’s inside, to a separate folder, that way you can check if that particular sound file is working with your system sound player and help us validate if it has been actually corrupted.

If you’re just starting out with Pencil2D, the development team has been fixing a few bugs that have to do with saving and loading. Release version 0.6.2 and anove should minimize these issues download it here: http://pencil2d.org/download
However, In the event that you find yourself running upon those rare issues, please consider the following to prevent losing and, in some specific scenarios, also recover your work:
Always create backup copies of your work file BEFORE loading and AFTER sav…

It’s also important that you consider using a recent development build to get as many of the latest fixes as possible. To get a recent development build visit the following link: http://pencil2d.org/download#nightlybuild there’s always a trade-off when using the “nightly builds” as sometimes they are more stable than the current release, but sometimes they are far worse. In this case the most recent version from October 14th is really stable and the copy paste issue that was mentioned is also fixed.
